[PATCH 21/32] bcache: set bi_op to REQ_OP
From: mchristi
Date: Wed Nov 04 2015 - 17:16:26 EST
From: Mike Christie <mchristi@xxxxxxxxxx>
This patch has bcache set the bi_op.
For compat reasons, we are still ORing the op into bi_rw. This
will be dropped in later patches in this series when everyone
is updated.
